TPO (Thermoplastic Polyolefin) is a single-ply roofing membrane used on flat and low-slope commercial roofs. It consists of a reinforced thermoplastic sheet that is heat-welded at the seams to form a continuous, watertight surface. TPO is valued for its energy efficiency, durability, and cost-effectiveness.

How long does a TPO roof last in Miami?

A properly installed TPO roof in Miami typically lasts 20-30 years. Factors that influence lifespan include membrane thickness (60-mil vs 80-mil), exposure to UV and chemical agents, ponding water management, and maintenance frequency. Thicker membranes and proper maintenance maximize longevity.

Is TPO better than EPDM for Miami commercial roofs?

For most Miami applications, TPO offers advantages over EPDM: it is white and reflective (reducing cooling costs), its seams are heat-welded (stronger than EPDM's glued or taped seams), and it offers better chemical resistance. EPDM can be a good choice for certain applications, but TPO is the preferred membrane for South Florida's climate.

How much does a TPO roof cost in Miami?

TPO roofing installation in Miami typically ranges from $6 to $12 per square foot depending on membrane thickness, insulation requirements, attachment method, and warranty level. Larger buildings benefit from economies of scale. We provide detailed estimates tailored to your specific project.

Can TPO be installed over an existing flat roof?

In some cases, TPO can be installed over an existing single-ply membrane if the deck is in good condition and local code allows it. However, if moisture is trapped in the existing insulation or the deck is deteriorated, a full tear-off is recommended. We perform moisture scans to make this determination.

Does TPO roofing meet Miami-Dade HVHZ code?

Yes. The TPO systems we install carry Miami-Dade NOA (Notice of Acceptance) product approvals for use in the High-Velocity Hurricane Zone. This means they have been tested and approved for the wind uplift forces specified by the Florida Building Code for this region.

What maintenance does a TPO roof need?

We recommend biannual inspections, drain clearing, and prompt repair of any punctures or membrane damage. Keeping the roof free of debris and ensuring proper drainage prevents most common issues. Our commercial maintenance programs make this easy and affordable.

What is the difference between mechanically attached and fully adhered TPO?

Mechanically attached TPO uses fasteners and plates to secure the membrane to the deck, and is generally more economical and faster to install. Fully adhered TPO is bonded to the insulation with adhesive, providing a smoother appearance and potentially better wind uplift resistance in high-wind zones. We recommend the attachment method based on your building's specific requirements.

TPO Roofing Services in Miami & South Florida

TPO (Thermoplastic Polyolefin) has become the dominant single-ply membrane for commercial flat roofs in Miami and throughout South Florida, and Extreme Roofing Inc. is one of the region's most experienced TPO installers. TPO delivers the ideal combination of durability, energy efficiency, chemical resistance, and affordability that commercial building owners and property managers demand.

Our certified applicators install TPO membranes from Carlisle SynTec, Firestone, GAF, and Johns Manville in 60-mil and 80-mil thicknesses using mechanically attached, fully adhered, or ballasted application methods depending on your building's structural requirements and warranty goals. Every seam is hot-air welded to create a monolithic, watertight bond that is actually stronger than the membrane itself.

TPO's bright white reflective surface is particularly advantageous in Miami's tropical climate, where it can reduce rooftop temperatures by up to 60 degrees compared to a dark roof, significantly cutting air conditioning costs and reducing urban heat island effects. When paired with rigid insulation board, TPO systems deliver exceptional thermal performance and can contribute to LEED certification credits. We also offer TPO in light gray and tan for projects where aesthetics are a consideration.

Why Choose Our TPO Roofs?

Backed by 22+ years of South Florida expertise, our team delivers results you can count on.

Cool-Roof Performance

TPO's highly reflective white surface reduces rooftop temperatures by up to 60 degrees, cutting cooling costs and qualifying for energy rebates.

Welded Watertight Seams

Hot-air welded seams create bonds stronger than the membrane itself, providing superior leak protection even in ponding conditions.

Chemical & UV Resistant

TPO resists ultraviolet degradation, ozone, chemical exposure, and biological growth -- ideal for Miami's harsh environmental conditions.

Cost-Effective Solution

TPO delivers premium flat-roof performance at a lower cost than PVC while offering comparable durability and energy efficiency.

NDL Warranties Available

As a certified applicator, we offer 10, 15, 20, and 25-year no-dollar-limit manufacturer warranties covering materials and labor.

Our Process

A straightforward, transparent process from start to finish -- no surprises.

Roof Survey & Specification

We evaluate the existing roof or new deck, assess drainage, and specify the TPO system thickness, attachment method, and insulation package.

Surface Preparation

The existing membrane is removed if required, the deck is cleaned and repaired, and rigid insulation is installed to achieve the target R-value.

Membrane Installation

TPO sheets are positioned, mechanically fastened or adhered, and all seams are hot-air welded using robotic welding equipment for consistent quality.

Detail Work & Warranty

Penetrations, curbs, drains, and perimeter edges are flashed with TPO accessories. The completed system is inspected and the manufacturer warranty is activated.
